一城独大与省域经济增长的关系——以27个省、自治区为例

Relation between monocentricity and provincial economic growth:taking 27 provinces and autonomous regions for example

基于我国27个省区2000-2012年的样本数据,运用泰尔指数及其分解公式测算了各省区的省域城市空间结构类型,提出了省域城市空间结构的三种类型。在此基础上,分别采用面板固定效应模型和半参数估计模型对各省区单中心程度和经济增长之间的关系进行了检验。结果显示:单中心程度和经济增长之间呈现不同的非线性特征;从全国数据来看,单中心程度和经济增长之间表现为扁平的S型平滑曲线,并且总体上呈上升趋势;从沿海地区数据来看,单中心程度的提高会抑制省域经济增长;从内陆地区数据来看,单中心程度的提高会促进省域经济增长。

Based on the data from China＇ s 27 provinces from 2000 to 2012, using the Theil Index and its decomposition, this essay identifies the provincial spatial structure type and proposes three criteria. On the basis, this essay uses the Fixed Effect Model and Semiparametric Estimation Model to examine the relationship between monocentricity and economic growth. Results show that the relationship between monocentricity and economic growth is different nonlinear features. From the evi- dence of national data, the relationship between monocentricity and economic growth is characterized by a flat S - shaped smooth curve, and, in General, is on the rise. From the evidence of inland data, the increase of monocentricity will promote provincial economic growth.
